Application leaua'y 1a, 1914; serial No. sa'sgas's'.

To all 'whom t may concern.' y

Be it known that I, VICTOR E. STAEUBLI, a citizen of the United States, re'siding at Blaine, in the county of Whatcom and State of Vashington, have invented a new and' Vuseful Timepiece, of which the following the details of constructionl hereinafter de-j scribedl and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is'claimed without departingfrom the spirit of the invention.

In the drawings-jFignre 1 is a front elevation of a time piece having thevpresent attachment in use with the zero marks adjacent to the Greenwich meridian time. Fig. 2 is a similar view'showing the present at` tachment in the position it assumes'in the locality of eastern time in the United States. Fig. 3 isa cross section through the forward portion of a clock showing the present attachment mounted and byy means of which the same may be moved to adjust the meri` dian time relatively to the time dial. Fig. 4 is a view illustrating a modied arrange"- ment of the present dial. Fig. 5 is an enlarged detail showing the method of placing thel numerals' by etchingor otherwise Figs. 6 and 7 are perspective views showing the relative positions of the zero points of the scales on the crystal and the markings on thedial which indicate the meridian of reference.

Referring to the drawings, and more particularly to Figs. 1, 2 and 3 thereof, the numeral `1 designates the time piece casing, provided with the usual dial 2, the hour hand 3, and the minute hand 3, the crystal 4 in the present instance being detachably connected for independent rotation or adjustment by means of the clamping band or ring 5 and or be of any desired construction which will permit of the dial or crystal 4 to be adjusted, the purpose of which will presently' appear.

The crystal 4 as shown is provided withv the-west longitude indication (Sand`` the east longitude" indication 7, the same being' arranged; concentric'of eachother with the de-V gree digits progressively increasing" from the zero or at thev date line 8 in opposite d1re`ctions, thisindic'ation therefore including 180|` degrees so as to conform to the twelve hour movement of the time" piece.

As shown in Fig. 401 thelcdrawings, the west longitude indication 6 and the east longitude indication 7 is disposed upon the crystal 4 within the time figures ofthe time dial 2', such crystal 4 being adjustable simi-j lar to the crystal 4 heretofore described and being provided: withV the hour' points 9f and 10'opposite the dateline'S sothat the same will more readily point to the desired hour' when thedial is adjusted o In describingfthe use ofthe present invention, Figs-1,2 and 3 will be referred to, the date or zero line of the dial shown in Fig. 1 being disposed at meridian time, or-

what is commonly known as zero longitude or' Greenwich time. The dial as shown in- Fig.Y 2" is set for 7 5 degrees West longitude or eastern time inthe United States, while the dial shown in Fig. 4 is set for 120' degrees west longitude or Pacific time in the United States; l

The date lines' nv the dialsI inf both' forms of the invention may be described as markings indicating the meridian of reference.

In setting the respective dials 4 andy 4 to correspond with the located standard time or meridian time, lthev disk'is revolved forward until the number correspondingz with Ehe designated meridian is dir/@HY over and 1n line wlth noon orV` twelve. O "ClfOC-kl on the dia-1 of. the time piece. kThe haar hand a is:

therefore the principal indicator and when the clockl or watch hasbeen set t'o standard time for'the particular locality orA meridian, the same is readily usefuli and suggestive TheA hour hand`r will then point and' show the geographical location of the meridian sunf or high noon' for every standard timevmeridian both east and west longitude and' for all hours of the'- day,l and also the opposite or midnight meridian; Thus' with the clock in the'positionAv as shown inV Fig.Y 1,A the hourhand"y pointing to seven oclock or 105 degrees west longitude, thus indicates what would be the highmeridian or noon time at that particular locality, the same also pointingto 75` degrees east lbngitud'e, which' would indicate the midnight meridian in this'particular locality. By passing to a point diametrically opposite or 15 degrees west longitude, and 165 degrees east longitude, the time of sun setting and sun rising respectively, allowing however for the uaA equal day and night will be in dicated for those particular localities. Y,

In the dial as shown in Fig. 2, the hour and minute hands indicate Vapproximately one forty oclock while that shown in Fig 4L indicates ten forty oclock, so that the struc ture may be operated by keeping a memorized time location upon the moon, as shown for instance in the Printed Tide Tables of the United States Department of Commerce, Coast and Geodetic Survey, einimer-V ated rlable :tt-6 Moons rlransit and Equation ofTime, which shows Greenwich Mean Cii/'il rllime of the Moons Upper and Lower Transits and Equation Vof the Time, in which this table is compiled for every day throughout the year, itebeing noted that February 2nd, would show for the locality 120 degrees west longitude that the moon is 5 hoursV and 3G minutes Vbehind or distant from the sun.V Thus rby keepingv a memorized time location on the moon, that is approximately allowing or counting back, that many hours for the moonls distanceor meridian location, and whenever shownupon the disk, the tworfiffures upon the disk 41- or ll will show east and west longitudinal location for high water marks andthe opposite two figures will show'east and west longitudinal locations kfor the low water marks or depressions. KVTaking for illustration, the indication as shown in Figli, and counting Vback from the hour-hand which ismeridian sun live thirty or approximately, and arrive at figures on the dial 4e 15 degrees west and 165 degrees east longitude, the high-water mark .upon the open sea willV be indicated,

i the opposite numbers across the dial numbered 105 and 7 5 practically east and west longitude, will indicate the low water mark bythe clock dial., 1 Y Y The hourV hand indicates the .position at all times of the sun, meridian or midnight. 7eV will therefore Vassume the position of the sun to be at 165 degreeswestlongitude, the opposite or Imidnight at 15 degrees east longitude. As the hour hand or time passes on, we arrive at 180 degrees west or east longitude, the opposite or midnight at zero east or west longitude. rlhe hour hand or time passes on, and we arrive at 165 degrees easty longitude, which could also be used as 195 degrees west longitude, but as. it is never geographically referred to as 195 degrees west longitude, it is therefore 1G5- degrees.

- east longitude because of the figuring andY counting from zero to 1870 degrees both east Copies of this patent may 'be obtained for and west'. The position 180 can be read as east or west, if it is assumed to be the meridiansun, then zero east or west is midnight, but as the sun crosses lthe date line, the same is read east longitude. Upon the disk west longitude is indicated by the top line of ligures and east longitude is indicated by the parallel or bottom line of figures. Now if the sun be followed vfrom one revolution that is from Zero to 180 degrees and yinversely from 180 degrees to Zero, one full revolution of 360 degrees is had. VTherefore a twelveY hour time piece makes two reif'olutions covering this' same period and permits the counting of both east and west at one glance, thus permitting the location of the geographical'position of the sun, high noon or midnight, and longitude east or west.

Assuming that the time is always set at noon or high meridian at l/Vashington time, the disk is set at 75 degrees westand 105 east longitude to correspond with the twelve oclock or high meridian. Therefore 75 degrees westV longitude is the ,position of the sun and the opposite 105 degrees east lengt tude is the midnight meridian. As the time passes, and it arrives atl twelve oclock, the

hour hand points to the same figures, but

from the position of the longitude dial it is known that the meridian sun is at 105degrees east longitude and that 75Y degrees west longitude is midnight meridian.

lt will also be noted "that with'the present form of dial, that the same may be attached to any form of clock without in any way aifecting the hour-.or minute hand and the time dial. A y Y' Y lVhat is claimed is: Y Y A time piece embodying a dial having a time scale comprising twelve hour characfY ters; and a rotatable crystal housing ,the dial, the crystal being provided with east and west longitude scales reading in opposite directions from accmmon ,Zero point by 15 degree ,intervals which are coincidentV with the hour characters, the time scale and the longitude scales beinO concentrically dis 'A posed,the dial having a markingV indicating the meridian of reference, with which markmg thevzeropoint may be made vto coincide,

the space within the innermost of said con-1 centric scales being open and unencumbered to permita ready cross referencefrom any Vmarking on one longitude scale.: to a mark# ing 180 degrees remote therefrom.

ln testimony that I claimthe foregoing as my own, l have hereto aliixed my signature in the presence of two witnesses. y VICTOR E. STAEUBLI.
